Rotors Overall & for sloped portions of Yards

I am in the process of selecting my rotors for my new sprinkler system. I've heard good things about the RainBird 5000+ and the Hunter I-20 & PGP. I like the RB raincurtain feature and flexibility of adjustment, but hear good things about the Hunters. Any preferences here?

Also, my front yard is sloped so that I have about 10 of height difference in two of my zones. The I-20 have check valves and are cheaper than RainBird rotors that have check valves. Do I need check valves in all the rotors in these sloped zones?

You would probably only need a check valve at the end head so all the water doesnt drain out the bottom head when the zone is off. I like Hunter PGP, or the Rainbird 5000+. I have heard good things about the I-20 also.

Not only does the I-20 have checks in the seat it also has a flow control built into the head. You can even turn individual heads off with this feature. This allows you to fine tune certain areas and change out nozzles will the zone is running. They are my favorite.

One thing on the i-20 . Lets remember its necessarely a true flow control. Its main purpose is to shut off/on. I also use it to control my coverage but it will effect your head gpm rate and if you turn it down to low your rotation will slowwwww down.
